August marks the 18th consecutive month of rising home prices, according to FNC’s Residential Price Index released Tuesday, indicating an indisputable recovery. However, FNC, a mortgage industry technology provider, is detecting some deceleration in the recovery and declares, “It is clear that the recovery remains uneven across the nation.”

On a monthly basis, prices rose 0.6 percent in August, according to FNC’s composite of 100 large metropolitan areas. On a yearly basis, the increase is 5.3 percent. The monthly gain in August was smaller than the gains accrued over the two previous months.

San Antonio, Texas, topped the 30-market list with a 2.1 percent gain, followed by Las Vegas with a 1.8 percent gain. Charlotte, North Carolina, and New York tied for third place with a 1.5 percent price gain over the month.

“This softening price trend in Phoenix and Los Angeles—two of the housing market’s most important barometers—emerged after a long streak of rapid price accelerations that averaged more than a 2.0% month-over-month increase,” FNC stated.

FNC also noted that while the Chicago market “is on the mend,” it is lagging all other markets in the index in terms of price appreciation.
